Background

Pneumothorax (pneumothorax) refers to the state of pneumatosis resulting from the entry of air into the pleural cavity, known as pneumothorax. The lung tissue and visceral pleura are ruptured due to lung diseases or external force influence, or tiny emphysema bubbles close to the surface of the lung are ruptured, and air in the lung and bronchus escapes into the pleural cavity. Those caused by chest wall or lung trauma are called traumatic pneumothorax; spontaneous pneumothorax is caused by the self-rupture of lung tissue due to diseases, and artificial pneumothorax is called when air is artificially injected into pleural cavity for treatment or diagnosis.

On the battlefield, the fighter is injured due to the complex battlefield environment or can cause the situation of pneumothorax due to the physical factors of the fighter, the situation is critical on the battlefield, the fighter cannot be sent to a nearby hospital in time, the medical care personnel at the side usually are non-professional respiratory doctors, the situation of the pneumothorax cannot be handled in time, and the life safety of the fighter is easily threatened.
